TROUBLE SHOOTING
In most cases, rare operational difficulties are the result of a weak transmitter battery. Below are the
guidelines for solving the majority of the problems you may encounter. If you have not solved the problem
after following these guidelines, contact a professional installer immediately.
1. No siren sound or chirp when transmitter button is pressed for arming or disarming:
a. Make sure the alarm's RED wire has power, and the BLACK wire is properly grounded.
b. Replace the transmitter battery and check the clips for proper polarity.
c. Recode the remote — see "Code learning."
2. Transmitter works in some areas and not in other areas:
This is probably due to excess RF activity in that area (usually just a short time and only while you are
in that area, depending on the type of the activity). It is only temporary and won't affect the alarm in
other areas.
3. Alarm sounds for no apparent reason:
a. Be sure that the transmitter button #1 is not being held down too long, or something in your pocket
or purse is not pressing against the transmitter button #1. The receiver may also be picking up
interference from a nearby airport, low-flying plane or other sources. Such interference is
temporary.
b. Check which zone was triggered — see "Triggered zone indicator."
4. No chirp when arming, (lights flash 4 times and central locking operates VS255XR) Refer to VALET
instructions to exit Valet Mode.
Important: Do not make any repairs or adjustments to any component of the transmitter or the alarm other
than changing the battery or checking the shock sensor adjustment as described.
